Balancing Machine for Crankshafts

  • Universal machine concept
  • Automatic unbalance measurement
  • Precision positioning during correction
  • Microprocessor-controlled measuring unit

Design

Two-station machine with separate measuring and correction stations. Measuring station with coupling-free roller-drive or hook drive for asymmetrical crankshafts.
Correction station with positioning equipment and electro-mechanical drilling equipment.

Range of application

Measurement and correction of unbalance in machined passengervehicle and light commercial- vehicle crankshafts. Use in small and mid-volume series production or as a repair balancing machine.
Unbalance correction by drilling into the counterweights in one or more steps at a separate drill stand (correction station). Manual handling of the work-pieces between measuring and drilling stations.

Sequence of operations

  • Load a crankshaft into the measuring station, manually or by lifting device
  • Close the protective shroud. Automatic measuring run and display measured values.
  • Open the protective shroud and move the crankshaft to the correction stand.
  • Insert the crankshaft into positioning device and couple with angleencoder for optional indexing aid or with locking-pin device
  • Drill correction holes one after another corresponding to the display
  • Return the crankshaft to the measuring station. Automatic check run and display of residual unbalance.
  • Remove the crankshaft. If the crankshaft is still out of tolerance proceed with a second step.
